I have recently purchased Fildisi theme and I have linked the envato market plugin with the right oauth token however WPbakery plugin packed with it is using the version 6.4.0 while the latest version is 6.4.5 where a critical vulnerability has been patched in it.
What is the formal way for wpbakery to be updated? It cannot be done from the plugin pannel.
here you have an article regarding updating bundled plugings like page builder . The article can be found on the documentation site of theme Fildisi.
Alternatively you can contact the author of the item in case needed.
